Default How Einsteinians Prove Time Dilation

"But the fact that you can see cosmic ray muons at all is enough to prove that relativity is real. Think about where these muons are created: high in the upper atmosphere, about 30-to-100 kilometers above Earth's surface. Think about how long a muon lives: about 2.2 microseconds on average. And think about the speed limit of the Universe: the speed of light, or about 300,000 kilometers per second. If you have something moving at the speed of light that only lives 2.2 microseconds, it should make it only 0.66 kilometers before decaying away. With that mean lifetime, less than 1-in-10^50 muons should reach the surface. But in reality, almost all of them make it down. Why? From our point of view (or frame-of-reference), because of time dilation." https://www.forbes.com/sites/startsw.../#2d4768797008

The lie here is that the muon "lives 2.2 microseconds" (Einsteinians call this "lifetime of muons at rest"). Actually this is the disintegration time amidst the molecules of a solid body, after the muon crashes into the detector at a speed close to the speed of light. Comparing this postcatastrophic short amount of time with the lifetime of muons in a vacuum which have not undergone a catastrophe is possible only in Einstein's schizophrenic world:

"The lifetime of muons at rest [...] Some of these muons are stopped within the plastic of the detector and the electronics are designed to measure the time between their arrival and their subsequent decay. The amount of time that a muon existed before it reached the detector had no effect on how long it continued to live once it entered the detector. Therefore, the decay times measured by the detector gave an accurate value of the muon's lifetime. After two kinds of noise were subtracted from the data, the results from three data sets yielded an average lifetime of 2.07x 10^(-6)s, in good agreement with the accepted value of 2.20x 10^(-6)s."

"In order to measure the decay constant for a muon at rest (or the corresponding mean-life) one must stop and detect a muon, wait for and detect its decay products, and measure the time interval between capture and decay. Since muons decaying at rest are selected, it is the proper lifetime that is measured. Lifetimes of muons in flight are time-dilated (velocity dependent), and can be much longer..."

Default How Einsteinians Prove Time Dilation

The GPS fraud:

One calculates the distance between the satellite and the receiver by multiplying the time by Einstein's constant speed of light, obtains a wrong value (because the speed of light is variable, not constant), "adjusts the time" in order to fix the wrongness, and finally Einsteinians inform the gullible world that Einstein's relativity (time dilation) is gloriously confirmed:

http://www.wired.com/2011/06/st_equation_gps/
"Your GPS unit registers the exact time at which it receives that information from each satellite and then calculates how long it took for the individual signals to arrive. By multiplying the elapsed time by the speed of light, it can figure out how far it is from each satellite, compare those distances, and calculate its own position. [...] According to Einstein's special theory of relativity, a clock that's traveling fast will appear to run slowly from the perspective of someone standing still. Satellites move at about 9,000 mph - enough to make their onboard clocks slow down by 8 microseconds per day from the perspective of a GPS gadget and totally screw up the location data. To counter this effect, the GPS system adjusts the time it gets from the satellites by using the equation here. (Don't even get us started on the impact of general relativity.)"
